Per Cell Kernels

[Joshua Marshall Moore]

Hey wouldn't it be great if the kernels could work on a cell level, so that different installed kernels can run in the same notebook, say bash, python, and javascript. 

[Thomas Kluyver]

There are some options for doing this at the kernel level - e.g. in an IPython kernel there are extensions to let you use %%R and %%julia cell magics. Then there are things like the Script-of-Scripts kernel: https://github.com/vatlab/SOS .

There's also a notebook project called Beaker which aims to support mixing languages in a notebook.

At the Jupyter level, however, the model is that one notebook has one kernel.

Thanks Joshua and Thomas, yes Beaker Notebook has that capability,

but we stopped developing it in favor of BeakerX which is an extension to Jupyter Notebook.

This feature is now on the agenda: https://github.com/twosigma/beakerx/issues/6279

Indeed the plan is to use a kernel that proxies other kernels, like SOS.

Then we can use Arrow (https://github.com/apache/arrow) for autotranslation of data between the kernels.

BeakerX does already support autotranslation from Python to JavaScript (good for working directly with D3):

http://nbviewer.jupyter.org/github/twosigma/beakerx/blob/master/doc/contents/autotranslation_python.ipynb

Python has a Bash magic too, so the particular combo you ask for can actually be done today with BeakerX.

Best, -Scott

Or you could add those functions via cell magics.
